Application `filed .T anuary 28, 1918. Serial No. 214,112.

T0 all whom it may concern Y Be it known thatI, FREDERICK VVILLsoN,

a citizen of the United States, residing at.

Reading, in the county of Berks and State Fennsylvania, have inventedcertain new and useful Improvements in Goggles, of which the followingis a specification.

My invention relates particularly to spectacles or goggles havingfolding eye-guards, and it 'consists mainly in improved lensclampingmeans andguard connections as fully described by reference to theaccompanying drawings, and the novel features of which are pointed outin the claims.

Figure 1 is an edge vview of a pair of goggles embodying myimprovements; one of the lens framingsand its attached guard being shownin section on the line -I of Fig. 3, with the guard in folded positionand the clamping device removed from the end-pieces; and the other beinga full edge Y view with the parts inposition for service.

Fig. 2 is a separate view of the clamping device' and its pivotedcarrierbar; the head band being shown in engagement with the free end ofthe latter, and also with the side guard, as illustrated in Fig. 1. y

Fig 3 is a. partial outer-face view of one of the lens framings, showingthe engaged clip band and one of the end-pieces in section.

Each lens framing, as shown, comprises a split lens-edge engaging frame5 having pair of projecting end pieces 6 6, which are brought togethertoclamp the lens and spreadable to release the same. This lens frame 5is formed with an inwardly turned marginal flange 8 arranged inlens-reinforcing contact with the rear face of the lens as set forth inmy Patent No. 1161100 issued November 23, 1915, so as to safely retain afractured lens; said-flange serving also in the present structure forconveniently securing thereto, by so-called pin-welding or otherwise,the separately formed flange guard ring 10; to which latter an ordinaryflexible side guard 11 is rigidly secured so as to permit of folding ittoward the inner face of the lens as indicated in Fig. 1. The head band12 for securing the completed goggles is attached to the free end ofeach guard, by means of a rigid end bar 13 on the band, which bar isengaged with an integral strip 14: of the guard formed by parallel slitsin the latter in well known .man-

ner.

My improved lenssclamping means and guard connection comprises alocking-clip band 16 formed of a sheet metal strip bent to encircle andclamp together the abutted end-pieces 6--6 of the lens framing; the

y free ends of thevspring band thus formed being normally in parallelrelation and provided with apertures to form a pivoting jaw 17 in whichone end 18 of a carrier bar 19 is pivotally engaged; and the portion ofsaidband engaging the end-pieces having an inwardly `projecting tit 2()adapted to engage a recess or aperture in an end-piece as indicated inFig. 3 so as to normally retain the band in its clamping position.

The pivoted carrier bar 19 is movable with the folding side guard 11 asindicated, and is connected to the latter at its opposite end 25; thisconnection, as shown, being ef fected through the medium of the headband 12, which is directly attached to the guard as previouslydescribed, by Stringing said band through the transverse slot formed inz said end 25 of the bar.

My invention thus provides that when the clip band 16 is detached fromthe end piece 6 it will be carried by its pivotally connected carrierbar 19, which bar is itself connected to the guard 11 by means of theband 12 attached to the latter; so that each clip band 16 may be readilyremoved from the end pieces, when it is desired to release the-lens, yetremain Vattached to the corresponding guard 11'; while when the clipband is normally attached to the end pieces, said carrier bar 19 freelyturns in the pivoting jaw 1T of the clip band and permits it to folddown with the guard 11, and also gives support to the latter when bothare thrown out to operative position; the tension upon the head gagedspringchp band on the abutted endpiece. membersformed with a locking titand a pivoting jaw.

2. In an eye protector, the combination with a lens-edge framingprovided With a pair of extending end-piece members, and with a sideguard foldably attached to said framing; o'f a detachable locking-clipband for the abutted end-piece members formed With a pivoting-jaw, and acarrier bar for said clip band connected at one end to said jaw and atits other end to the foldable side guard..

3. In 'an eye protector, the combination with a lens-edge framingprovided with a pair of extending` end-piece members, and with a sidegnard foldably attached to said framing; of a detachable locking-clipband for the abutted end-piece members `formed with a pivoting jaw, acarrier bar for said clio band connected at one end to said jaw, ani ahead band oonnectedto the outer portions of said foldable guard andcarrier bar. p
